DZL
packaged water-tube steam boiler is the double-cylinder,water-tube
assembly,chain grate boiler.Two cylinders are laid at the upper and
lower level of boiler longitudinally along the center.Front section
of the upper cylinder and water-cooled tubes at side walls form the
radiation-heating area in the hearth.While the rear section and
tube bank in the lower cylinder serve as convection-heating
area.Coal econnomizer is mounted at the rear of bolier.Some heat of
hot combustion fume is absorbed by the hearth.Then hot combustion
heat flows to the convection heating area through cooling chamber
and exhausts outside with the chimney via coal economizer,dust
collector and draught fan.� Compact
soize,small installation spaxe,single-floor boiler
room,cost-effective omfrastructure.� Great
assembily level,short installation period and cheap
installation.� Sufficient
and reasonable heating area,quick temperature/pressure-rise of
boiler,satisfactory productivity and high heating
efficiency.� Ntroduce
the air with air distribution chambers of grate.All air
distribution chambers can adjust the air flow indepedently and
grate speed can be regualated in the stepless way.Wide range of
applicable coals.Thorough combustion.� Electrical
cabinet is equipped with complete automatic control and monitor
instruments featuring high automation,safety,reliability and simple
operation.
